Training manual on improved tilapia culture and dyke cropping in pond/Gher

Due to inadequate technical knowledge and training in advanced methods of gradually growing tilapia culture, framers are not getting expected yield. From the very beginning of the CSISA-BD project, WoldFish Center has taken initiative to introduce advanced methods in tilapia culture. To do this, the shortage of skilled trainers and training materials, has, particularly, been realized. Presently, a number of manuals on tilapia culture from Department of Fisheries, Bangladesh Fisheries Research Institute, WorldFish Center and different GOs and NGOs are available.

Response to selection for growth in an interspecific hybrid between Oreochromis mossambicus and O. niloticus in two distinct environments

The development of a saline tolerant tilapia strain able to grow fast is of importance in the Philippines, where 240 000 ha of brackish water ponds are available. To this end, founder hybridization between Oreochromis niloticus (with favorable growth traits) and O. mossambicus (with favorable salinity tolerance traits) was performed and followed by backcrossing with O. mossambicus to develop a strain highly tolerant to saline environments. Genetic selection for growth performance was subsequently conducted.

Relative performance of two Nile tilapia (Oreochromis niloticus Linnaeus) strains in Egypt: The Abbassa selection line and the Kafr El Sheikh commercial strain

The Abbassa selection line (developed by selective breeding) and the Kafr El Sheikh commercial strain (widely used in Egypt), both Oreochromis niloticus, were compared at two stocking densities (two and four fish m-2). Harvest weight, length, depth, width and head length were recorded. The Abbassa line showed a superior harvest weight (28 per cent) over the Kafr El Sheikh strain. Males were heavier than females, but the between-sex difference was greater in the commercial than in the Abbassa line (39 and 31 per cent respectively).

Kenya pioneers intensive tank culture of tilapia

Although it appears that the first recorded, scientifically oriented culture of tilapia was conducted in Kenya in 1924,of the current 30,000 ponds with a potential annual production of more than 7,000 tons, only 10% are functional producing 500 tons/annum. Tilapia tank culture at Baobab Farm is described in detail. The economics and prospectsof intensive culture in Kenya are considered.

Introducing the tilapias

The tilapias are a group of African, freshwater herbivorous fish that care for their young. Their name is derived from an African Bushman word simply mean-ing fish. There are about 70 species, most of them native to western rivers of Africa. Their herbivorous diet, depend¬ing on the species, ranges from coarse vegetation, such as grasses and leaves of water weeds, to unicellular algae and bacteria. This article takes a brief look at a few species of Tilapia and its culture.

ICLARM and South-south technology transfer: Philippine aquaculture technology and Indonesia Part I.

A historical account is given of the discovery of Tilapia mossambica and its culture in Indonesia and the resulting success in Java of this species in rural development programs. Consequent introduction of this species to the Philippines and development of the tilapia culture industry is described, comparing it with development of the industry in Indonesia.
